Replying to another bot's message and running /alias answered with the
list of kinds that can be saved, which blames the format of a message
the bot was never shown — it may well have been a photo. Telegram strips
the content of another bot's message, and the sender is not always marked
as a bot: an anonymous or service-posted message arrives equally empty,
so the existing bot check missed it.
Judge on whether any content arrived instead. A reply with no content
field at all, and a command that arrives with no reply attached, now both
say what happened and end with the one action that works: forward the
message into the chat and reply to your own copy. A reply that did arrive
with content of a refused kind — a poll, a location — still gets the list
of supported kinds.
One contentFields table backs both the check and the alias_capture debug
line, so the log line always explains the refusal the caller was given.
Text and caption formatting now survives an alias. Bold, italic, code, links
and mentions are stored as entities beside the text and sent back with it, on
the /insert, bare-command and inline paths alike. This works because the text
is re-sent byte-identical, so the offsets the entities carry stay valid — the
earlier comment claiming otherwise was wrong. They go back as entities rather
than re-rendered markup, which avoids escaping and re-parsing content the user
never wrote as markup.
/aliases now lists one line per name with what it holds, so the list says what
each will send:
3 aliases:
/cheer — sticker
/clip — video
/greeting — text
That costs one store read per listed alias, since DocStore has no bulk get and
the kind lives in the document. The reads stop once the message is full, so the
cost is bounded by what fits in one reply rather than by how many aliases exist.
Every reply that names a command or an alias wraps it in <code>, so tapping it
copies something ready to send. The generic usage lines stay plain text: they
contain a literal <name> placeholder that HTML mode would swallow as a tag.
Replying to another bot's message gets its own refusal. Telegram delivers that
reply with the content stripped, so capture finds nothing and the format advice
read as if the wrong kind had been sent. Checked only after capture fails, so
this bot's own messages — which are readable — never reach it.
/alias <name> saves a replied message under a name and /insert <name> sends it
back; /aliases lists every name and /unalias deletes one. Every Telegram format
is supported — sticker, photo, GIF, video, video note, audio, voice, document,
plain text — and each is kept as the file_id Telegram already issued, so nothing
is downloaded and an alias survives redeploys. The namespace is global and the
last assignment wins, matching the shared sticker pack; /unalias is open to
anyone for the same reason.
A saved name also works as its own command: /cheer rather than /insert cheer.
This needs two new seams in the module contract. Module.Fallback handles a
/command no module registered, and the dispatcher installs it after every
Command — the bot library returns the first matching handler, so code always
beats a name resolved at runtime, including an alias that shares a command
added in a later build. /alias refuses a name already in the registry for the
same reason, since such an alias would only reach /insert. An unknown command
stays silent: the fallback sees every unrecognised /foo in every chat, so
replying would make typos noisy and would confirm which names exist.
Module.Inline answers inline-mode queries — "@botname <prefix>" from any chat,
filtered by prefix and capped at Telegram's 50 results. Each result is a cached
inline type carrying the stored file_id, so the picker renders real previews
without an upload. Video notes are omitted because Telegram defines no
InlineQueryResultCachedVideoNote and substituting a plain video would change
what was saved. Inline mode must be enabled in BotFather before Telegram
delivers these updates.
Both slots are single-occupancy with conflict detection at Build. Auth.Permits
learns the inline sender so a gated inline handler would not deny everyone.
Build's command indexing and slot claiming move into addCommands/addSingletons,
keeping it under the project's cyclomatic cap.
Also restores the sticker module: /addsticker moves back out of util, which has
no store, into internal/modules/sticker as its only command.
